Title: The POSSUMUS-Detector

Abstract content We present the newly developed Position Sensitive Scintillating Muon SiPM -Detector (POSSUMUS). This modular designed scintillation detector is capable to determine particle's position two-dimensional with resolution of a few mm for minimum ionizing particles. POSSUMUS is usable for large area trigger applications with few readout channels. The idea of this detector is to combine two trapezoidal shaped plastic scintillators to form one rectangular shaped scintillator rod. Each trapezoid in a rod is optically insulated against the other. In both trapezoids the scintillation light is collected by wavelength shifting fibers (WLS-fibers) and guided to Silicon-Photo-Multipliers (SiPM), where the light yield is detected. The SiPMs are located at opposite sites of each WLS-fiber, an automatic voltage adjustment allows for a stable gain of the detected light signals. Position resolution in the transverse direction is achieved by the geometric shape of the scintillators. The amount of light produced by incoming particles is proportional to their path length in the trapezoid and thus position dependent. The longitudinal position resolution, along the scintillator rod, is determined by the propagation time of light to either end of the rod. Because of its modularity, the POSSUMUS-detector can be used for trigger applications of different sizes with only few readout channels. By combining several scintillator rods, position sensitive areas from 100 cm2 to few m2 are achievable. In this talk we present a fully operating prototype of POSSUMUS, the multi-channel gain stabilization system for SiPMs and results for transverse and longitudinal position resolution
